Abstract

The invention discloses a novel polymer solar cell with a dual-electron transmission layer. The novel polymer solar cell comprises a transparent conductive substrate; an inorganic / organic material laminated electron transmission layer, wherein the electron transmission layer is of a laminated structure formed by an inorganic material nano zinc oxide and an organic material PFN, and zinc oxide is annealed with a rapid heat treatment method; a luminous absorption layer; a cavity transmission layer; and a metal electrode. The high-efficiency polymer solar cell can be prepared by a solution method, the cost is low, and the large-scaled production is facilitated. The novel dual-electron transmission layer is adopted, to that the good electric conductivity of the inorganic material is inherited, and an interface dipole layer generated by the organic matter facilitates the extraction and transmission of electrons. Rapid heat treatment is carried out on the inorganic material, the crystallinity of the material is further improved, and the electron mobility is increased. The polymer solar cell subjected to the rapid heat treatment and provided with the dual-electron transmission layer has the advantages that compared with a device using a single polymer layer as the electron transmission layer, the performance is improved by 23% and reaches 9.31%.

Description

technical field [0001] The invention belongs to the field of optoelectronic devices, and relates to a novel polymer solar cell with double electron transport layers, a processing method for the electron transport layer, and a preparation method for the polymer solar cell. Background technique [0002] Under the constraints of the current energy crisis and environmental pollution, the rational development of clean and sustainable new energy is the key to future economic and social development. As an inexhaustible environmentally friendly and pollution-free energy source, solar energy stands out from many new energy sources. At present, crystalline silicon solar cells are dominant in the market, and their production technology is very mature. However, crystalline silicon solar cells are faced with a single source of materials and are heavily dependent on the purity and quality of materials. At the same time, the production process of crystalline silicon solar cells is itself a...
